Shelter-in-place may be implemented as a strategy for suppressing or mitigating an epidemic, for reducing numbers of critically ill patients presenting at the same time and for thus reducing the impact of critical illness on health care systems and reducing the likelihood that a surge in illness will overwhelm critical care resources. Shelter-in-place may apply specifically to individuals or groups judged to be at-risk for death or serious complications if infected, and contrasts with self-isolation (voluntarily seclusion at home to prevent infecting others) and 364:

After an announcement that the shelter in place is over, residents should go outside and open all doors and windows to ventilate the shelter. Similar processes should be followed in cars, workplaces, or schools.
